Building Renovation

The CD Howe Building is a large Downtown Class “A” Office Complex covering an entire City block. As this Crown Asset is 30 years old, a need was identified to completely renovate this fully occupied building.  The renovation and upgrade schedule commenced in 2002 and was completed in 2012, with a total construction cost of $140 million. This 1 Million ft2 facility is comprised of 11 above grade office floors, located in 2 towers (33,000 ft2), 3 commercial / retail levels and 2 below grade parking levels.

Our team commenced this project with a detailed investigation of the existing premises which would facilitate the development of a Master Plan and Design Guidelines for the modernization and reconditioning of the complex.   Our work included full base building systems upgrades as well as interior renovations for large government tenants which include Industry Canada, House of Commons and the Office of the Auditor General.

Total Project Budget: $140 million

 

Roof Replacement

PWGSC commissioned our firm to evaluate replacement of existing roofing membranes within the focus of a lifecycle retrofit program of the 100,000 ft2 roof. The existing 27 year old roofing membranes were beyond their working life.

The project utilized Energy Star roof-compliant high reflectance technologies on the upper mechanical roofs and green roofing technologies for the main 80,000 square foot roof area. The project also utilized leak detection technology over the entire landscaped area.
